To investigate the efficacy of transcranial direct (tDCS) or alternating current stimulation (tACS) in boosting cognitive training efficiency healthy older adults. We further explored whether such improvements depend on general performance age. In this randomized, sham-controlled study, 59 elderly participants (mean age 71.7) were assigned to receive computer-based (10 sessions, 50 min, twice w...

OBJECTIVE To investigate any additional effect of dual transcranial direct current stimulation (tDCS) compared with single tDCS in chronic stroke patients with aphasia. METHODS Eleven chronic stroke patients (aged 52.6±13.4 years, nine men) with aphasia were enrolled. Single anodal tDCS was applied over the left inferior frontal gyrus (IFG) and a cathodal electrode was placed over the left bu...

Adults struggling with low reading skills are underserved by limited available treatments. While brain stimulation techniques such as transcranial direct current stimulation (tDCS) has the potential to improve a variety of cognitive functions, little work has been done examining its potential to treat reading disabilities. Research on the effects of tDCS on reading abilities has been somewhat i...

BACKGROUND Transcranial direct current stimulation (tDCS) enhances treatment outcomes post-stroke. Feasibility and tolerability of high-definition (HD) tDCS (a technique that increases current focality and intensity) for consecutive weekdays as an adjuvant to behavioral treatment in a clinical population has not been demonstrated. OBJECTIVE To determine HD-tDCS feasibility outcomes: 1) abilit...

objective: recent studies on treating obsessive compulsive disorder (ocd) have investigated noninvasive brain stimulation techniques such as transcranial direct current stimulation (tdcs) to improve patients’ impaired emotion and cognition. however, such experiments have yielded mixed results, especially with respect to cognition. this study aimed to investigate whether anodal and cathodal tdcs...

This paper aims to design thermal dummy cells (TDCs) that can be used in the development of lithium-ion battery management systems. Based on physical property and geometry real 18,650 cylindrical cells, a three-dimensional model TDCs was designed, it is numerically simulate performance TDCs. Simulations show TDC mimic temperature change surface cell both at static dynamic current load. Experime...

In Brief High-definition transcranial direct current stimulation (HD-tDCS) of brain areas related to pain processing may provide analgesic effects evident in the sensory detection and thresholds. The somatosensory sensitivity was assessed after HD-tDCS targeting primary motor cortex (M1) and/or dorsolateral prefrontal (DLPFC). Eighty-one (40 females) subjects were randomly assigned 1 4 anodal p...

Anodal transcranial direct current stimulation (a-tDCS) of primary somatosensory cortex (S1) has been shown to enhance tactile spatial acuity, but there is little information as to the underlying neuronal mechanisms. We examined vibrotactile perception on the distal phalanx of the middle finger before, during, and after contralateral S1 tDCS [a-, cathodal (c)-, and sham (s)-tDCS]. The experimen...

OBJECTIVE We propose the use of a new montage for transcranial direct current stimulation (tDCS), called concentric electrodes tDCS (CE-tDCS), involving two concentric round electrodes that may improve stimulation focality. METHODS To test efficacy and focality of CE-tDCS, we modelled the current distribution and tested physiological effects on cortical excitability. Motor evoked potentials (...

Transcranial direct current stimulation (tDCS) has been used as a useful interventional brain stimulation technique to improve unilateral upper-limb motor function in healthy humans, as well as in stroke patients. Although tDCS applications are supposed to modify the interhemispheric balance between the motor cortices, the tDCS after-effects on interhemispheric interactions are still poorly und...
